Open camera using

I want to use the intention to open the camera in android

I used the following code, but when I click the button (the action of which acts onclick (), the applications close on themselves

public void onclick(int actionCode){ Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(takePictureIntent, actionCode); } public static boolean isIntentAvailable(Context context, String action) { final PackageManager packageManager = context.getPackageManager(); final Intent intent = new Intent(action); List<ResolveInfo> list = packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY); return list.size() > 0; }

If anyone can help please give me the full code

try this code

 public static final int CAMERA_PIC_REQUEST = 1;//firstly define this Intent photo= new Intent("android.media.action.IMAGE_CAPTURE"); startActivityForResult(photo, CAMERA_PIC_REQUEST);

The parameter passed to the on-click method is of type View not int , as you show.

According to this tutorial, your onClick method should be as follows:

 public void onclick( View v ){ Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(takePictureIntent, CAMERA_PIC_REQUEST); }

Where CAMERA_PIC_REQUEST defined as (although I'm not quite sure why you need to statically hard-code this value in your application):

 private static final int CAMERA_PIC_REQUEST = 1337;


Update

CAMERA_PIC_REQUEST used to uniquely identify the return result on onActivityResult . Multiple startActivityForResult requests can be startActivityForResult at a time.

 protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == CAMERA_PIC_REQUEST) { if (resultCode == RESULT_OK) { tv.setText("Got picture!"); imageData = (Bitmap) data.getExtras().get("data"); ImageView image = (ImageView) findViewById(R.id.imageView1); image.setImageBitmap(imageData); } else if (resultCode == RESULT_CANCELED){ tv.setText("Cancelled"); } } }

I know this question is old and answered, but for those who ask how to get the image file? this decision.

 String ExternalStorageDirectoryPath = Environment.getExternalStorageDirectory().getAbsolutePath(); String targetPath = ExternalStorageDirectoryPath + "/DCIM/Camera"; File targetDirector = new File(targetPath); File[] files = targetDirector.listFiles() String ImagePath = files[ file.files-1 ].getAbsolutePath(); Bitmap bmp = BitmapFactory.decodeFile(pathName); ivImage.setImageBitmap( bmp );

Also, you do not need to add camera permissions to the manifest file.

It’s very easy to launch the camera from your Android application: just write the code of two lines in the onClick method

 Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(intent, CAMERA_PIC_REQUEST );

Add one constant field to your class (you can use any random number instead of 7)

 private int CAMERA_PIC_REQUEST = 7;

Please take a look at this code, this works fine with me

 //define the file-name to save photo taken by Camera activity fileName = "new-photo-name.jpg"; //create parameters for Intent with filename ContentValues values = new ContentValues(); values.put(MediaStore.Images.Media.TITLE, fileName); values.put(MediaStore.Images.Media.DESCRIPTION,"Image capture by camera"); imageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values); Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri); intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1); startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

also applies this method to read the image when you shot the image from the camera.

  //handling intent responses @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (resultCode == Activity.RESULT_OK) try { if (bitmap != null) {bitmap.recycle();} String[] proj = { MediaStore.Images.Media.DATA }; Cursor cursor = managedQuery(imageUri, proj, null, null, null); int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); cursor.moveToFirst(); imageUriString = cursor.getString(column_index); getContentResolver().notifyChange(imageUri, null); ContentResolver cr = getContentResolver(); try { bitmap = android.provider.MediaStore.Images.Media.getBitmap(cr, imageUri); imageButtonPictureShop.setImageBitmap(bitmap);

//this.uploadImage (); this.executeMultipartPost (); //this.uploadFile(imageUriString); } catch (exception e) {Toast.makeText (this, "Failed to load", Toast.LENGTH_SHORT) .show (); if (e.getMessage ()! = null) Log.e ("Exception", e.getMessage ()); else Log.e ("Exception", "Exception"); e.printStackTrace (); }

  } catch (Exception e) { if(e.getMessage() != null)Log.e("Exception" , e.getMessage()); else Log.e("Exception" , "Exception"); e.printStackTrace(); } super.onActivityResult(requestCode, resultCode, data); }
